7075-T6 Txhuas Alloy: Aircraft-Qib Lub zog rau kev siv heev
7075-T6 txhuas, muab los ntawmGNEE, yog zinc-raws li, siab- lub zog aluminium alloy renowned rau nws lub zog tshwj xeeb - rau - qhov hnyav piv. Qhov no ua rau nws nyiam cov khoom siv dav hlau, kev tiv thaiv, thiab lwm yam siab - kev siv cov qauv kev ntxhov siab xws li dav hlau tis thiab thauj khoom - cov kabmob. Nyob rau hauv cov nqe lus ntawm lub zog, nws feem ntau tshaj ntau me me steels thaum muab zoo heev qaug zog tiv thaiv. Txawm li cas los xij, cov hlau tsis muaj qhov tsim nyog thiab tsis zoo weldability nyob rau hauv T6 mob.
7075-T6 txhuas alloy, muab los ntawmGNEE, yog cov khoom siv muaj zog siab - siv dav hauv kev lag luam aerospace thiab kev tiv thaiv. Nws yog qhov tshwj xeeb tshaj yog muaj nuj nqis rau nws lub zog zoo tshaj - rau - qhov hnyav piv, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas txo qhov hnyav yog qhov tseem ceeb. Cov hlau kuj tseem muaj kev tiv thaiv corrosion zoo, tso cai rau nws ua kom ntseeg tau zoo hauv marine thiab lwm qhov chaw nyuaj.
Tsis tas li ntawd, 7075-T6 muab kev ua haujlwm zoo thiab ua tau zoo weldability, txhawb ntau yam txheej txheem tsim khoom. Nws tuaj yeem tsim nrog kev tswj xyuas kom zoo thiab xa cov khoom zoo tshaj plaws, uas ntxiv dag zog rau nws qhov tsim nyog rau kev thov cov txheej txheem thiab precision daim ntawv thov.
